XC74WL240ASR

CMOS Logic NCMOS Logic Dual Bus Buffer (Inverted 3-state outputs) NOperating Voltage Range : 2V ~ 5.5V NHigh Speed Operations NMSOP-8B Package : tpd =3.8ns TYP NLow Power Consumption : 2µA (max) ■Applications GPalmtops GDigital Equipment ■Description XC74WL240ASR is Dual Bus Buffer manufactured using silicon gate CMOS processes. The small quiescent current, which is one of the features of the CMOS logic, gives way to high speed operations which enables LS-TTL. With wave forming buffers connected internally, stabilized output can be achieved as the series offers high noise immunity. As the series is integrated into a mini molded, MSOP-8B package, high density mounting is possible. ■Features High Speed Operations : tpd = 3.8ns TYP (VCC=5V) Operating Voltage Range : 2V ~ 5.5V Low Power Consumption : 2µA (max) Small Package : MSOP-8B ■Pin Configuration G1 A1 ■Functions INPUT 8 7 6 5 VCC 1 2 3 4 MSOP-8B （TOP VIEW） G2 Y1 G H L L A X H L OUTPUT Y Z L H Y2 GND A2 H = High Level L = Low Level X = Don’t care Z = High Impedance ■Absolute Maximum Ratings PARAMETER SYMBOL VCC VIN VOUT IIK IOK IOUT ICC, IGND Pd Tstg RATINGS −0.5∼+6.0 −0.5∼+6.0 Ta=−40℃∼85℃ UNITS Ｖ Ｖ Ｖ mA mA mA mA mW ℃ 13 Power Supply Voltage Input Voltage Output Voltage Input Diode Current Output Diode Current Switch Output Current VCC, GND Current Power Dissipation (Ta=25℃) Storage Temperature −0.5∼VCC＋0.5 −20 ±20 ±25 ±50 300 −65∼＋150 Note : Voltage is all Ground standardized. 934 XC74WL240ASR ■Recommended Operating Conditions PARAMETER Supply Voltage Input Voltage Output Voltage Operating Temperature Input Rise and Fall Time SYMBOL VCC VIN VOUT Topr tr, tf 0∼100（VCC=5V） CONDITIONS 2∼5.5 0∼5.5 0∼VCC −40∼+85 0∼200（VCC=3.3V） UNITS Ｖ Ｖ Ｖ ℃ ns ■DC Electrical Characteristics PARAMETER SYMBOL VCC （V） 2.0 VIH Input Voltage VIL 3.0 5.5 2.0 3.0 5.5 2.0 3.0 VOH 4.5 3.0 4.5 Output Voltage 2.0 3.0 VOL 4.5 3.0 4.5 3 State Off-Leak Current Input Current Quiscent Supply Current IOZ IIN ICC 5.0 0∼5.5 5.5 VIN=VIH IOL=4mA IOL=8mA IOL=50μA VIN=VIL IOH=−4mA IOH=−8mA IOH=−50μA CONDITIONS Ta=25℃ MIN 1.5 2.1 3.85 − − − 1.9 2.9 4.4 2.58 3.94 − − − − − TYP − − − − − − 2.0 3.0 4.5 − − − − − − − − − − MAX − − − 0.5 0.9 1.65 − − − − − 0.1 0.1 0.1 0.36 0.36 0.25 0.1 2.0 Ta=−40∼85℃ MIN 1.5 2.1 3.85 − − − 1.9 2.9 4.4 2.48 3.80 − − − − − −2.50 −1.0 − MAX − − − 0.5 0.9 1.65 − − − − − 0.1 0.1 0.1 0.44 0.44 2.50 1.0 20.0 μA μA μA V V V V UNITS VIN=VIL or VIH, VOUT=VCC or GND −0.25 VIN=VCC or GND VIN=VCC or GND −0.1 − 13 935 XC74WL240ASR ■Switching Electrical Characteristics PARAMETER SYMBOL CL 15pF tPLH 50pF Propagation Delay Time 15pF tPHL 50pF VCC （V） 3.3 5.0 3.3 5.0 3.3 5.0 3.3 5.0 15pF tZL 50pF Output Enable Time 15pF tZH 50pF 3.3 5.0 3.3 5.0 3.3 5.0 3.3 5.0 tLZ Output Disable Time tHZ 50pF 50pF 3.3 5.0 3.3 5.0 3.3 5.0 tosHL Input Capacitance Output Capacitance Power Dissipation Capacitance CIN COUT Cpd 50pF − − − 3.3 5.0 − − − RL=1kΩ RL=1kΩ RL=1kΩ CONDITIONS Ta=25℃ MIN − − − − − − − − − − − − − − − − − − − − − − − − − − − TYP 5.6 3.8 8.1 5.3 5.6 3.8 8.1 5.3 5.4 3.6 7.9 5.1 5.4 3.6 7.9 5.1 9.5 6.1 9.5 6.1 − − − − 4 6 17 MAX 8 5.5 11.5 7.5 8 5.5 11.5 7.5 8 5.1 11.5 7.1 8 5.1 11.5 7.1 13.2 8.8 13.2 8.8 1.5 1 1.5 1 10 − − Ta=−40∼85℃ MIN 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 − − − − − − − MAX 9.5 6.5 13 8.5 9.5 6.5 13 8.5 9.5 6 13 8 9.5 6 13 8 15 10 15 10 1.5 1 1.5 1 10 − − （tr=tf=3ns） UNITS ns ns ns ns ns ns ns ns ns RL=1kΩ ns tosLH Output Pin Skew （Note） 50pF ns ns pF pF pF Note: tosLH and tosHL are the guaranteed parameters. tosLH = | tPLHm - tPHLn | , tosHL = | tPHLm - tPHLn | ■Noise Characteristics ( tr=tf=3ns ) Ta=25℃ SYMBOL CL VCC(V) 5.0 5.0 5.0 5.0 VOLP VOLV VIHD VILD 50pF 50pF 50pF 50pF CONDITIONS MIN − −0.8 − − TYP 0.5 −0.5 − − MAX 0.8 − 3.5 1.5 V V V V UNITS 13 PARAMETER Not functioning output maximum dynamic VOL Not functioning output minimum dynamic VOL Minimum dynamic VIH Maximum dynamic VIL 936 XC74WL240ASR ■Propagation Delay Time ITypical Application Circuit VCC VCC Pulse Generator ZOUT=50Ω INPUT OUTPUT G GND CL IWaveforms tr tf 90% 90% 50% 10% VCC PRR=1MHz duty cycle 50% tr=tf=3ns INPUT 10% 50% GND VOH OUTPUT 50% 50% VOL tPHL tPLH 13 937 XC74WL240ASR ■Output Enable Time, Output Disable Time ITypical Application Circuit VCC Pulse Generator ZOUT=50Ω INPUT VCC G VCC VOUT OUTPUT GND RL= 1kΩ CL VCC IWaveforms tf 90% tr 90% 50% 10% 10% VCC PRR=1MHz duty cycle 50% tr=tf=3ns INPUT 50% GND tHZ 90% tZH OUTPUT （A=GND） tZL 50% tLZ VOL VOH 13 OUTPUT （A=VCC） 50% 10% VOL 938
